FREE S95 Fire Alarm System Operation Questions and Answers
In a fire involving electrical equipment, which component of the fire triangle is targeted by a CO2 fire extinguisher?
A CO2 (carbon dioxide) fire extinguisher works by displacing oxygen around the fire, effectively suffocating the fire. By removing the oxygen component of the fire triangle, the fire is extinguished. CO2 is effective on electrical fires because it does not conduct electricity and does not leave residue.
In what situation would a Deluge System be appropriate for an outdoor area?
A Deluge System is used in high-risk areas where rapid and simultaneous water discharge is needed to quickly control fires. This system has open sprinkler heads and a deluge valve that releases water through all the heads in response to a fire alarm. It is not typically used for outdoor parking lots unless there is a specific high-risk situation.
In addition to having 6 extra sprinkler heads, what other tool must be available on the property for sprinkler system maintenance?
Along with having 6 extra sprinkler heads, the property must also have a wrench available. The wrench is essential for installing or replacing sprinkler heads, making it a necessary tool for maintaining the sprinkler system.
Which condition indicates that the OS&Y valve is properly maintained and functioning as intended?
A properly maintained and functioning OS&Y valve should show the stem extended when the valve is open, which also typically places the yoke in a vertical position. This configuration indicates that the valve allows water flow through the system. The valve's open status is visually confirmed by the extended stem.
Why is it important to correctly identify and use the oxygen hose color-coded blue in torch operations?
Correctly identifying and using the color-coded oxygen hose (blue) is crucial for safety in torch operations. It ensures that gases are properly routed to their respective torches and prevents the risk of accidental mixing of gases, which could lead to hazardous situations or equipment malfunctions.
